Hello, i'm tring to queue import an .ods file but it throws a queryException "MySQL server has gone away" when it is going to insert records in the jobs table. If i queue xlsx files it works as experted.

ps. without the queue there are no issues when importing ODS files

php 8.0.3
laravel 8.54
laravel excel 3.1

here is my script so far

// web.php

    Route::get('/', function () {
        try {
		$import = new ProjectsImport();
		$import->queue("excel/test-example.ods");

        } catch (\Maatwebsite\Excel\Validators\ValidationException $e) {
		dump($e->failures());
        }

	dd("Done");
    });

Even if i can open and edit the file with the OpenOffice without any issues it seems there are something funny with it because it's only that particular file that i can't import... So there is nothing wrong with the script above. i should have tried multiple files before posting a question. Sorry for any inconvenience
